The total weight of the Type 99 was around 1,000 kilograms fully assembled with it being 11 meters long and 7 meters wide. The craft itself was known for its excellent reliability. Its main strength was allowing the Imperial Japanese Army to mobilize its troops quickly and effectively through even the most treacherous waters with little set-up required. In fact, this design process was typical of most Japanese assault craft, with speed and ease of use being marked as high priorities. Around 5-7 men typically served in a fully crewed Type 99.
